It has been exactly three weeks since the tragic death of singing superstar George Michael .

In that time countless headlines have been written about the multi million-selling performer, with stories detailing alleged depression, addiction, medical intervention and family dramas.

But, the subterfuge aside, what do we know for sure about the Wham! star's unexpected passing?

Here are the facts...

Where and when?

The Hertfordshire-born performer, real name Georgios Kyriacos Panayiotou, died at his home over the 2016 Christmas period at the age of 53.

He was discovered by long-term boyfriend Fadi Fawaz, who had slept in his car the night before the tragedy and, upon discovering the body, called emergency services and - later - his cousin, Josh, in Australia.

The latter conversation - which heard him say "Oh God, I think he's dead" - took place as paramedics fought, unsuccessfully, to save the chart-topper. Fadi later helped police with their investigation by being interviewed for more than five hours.

A post-mortem was conducted in early January, but was deemed inconclusive.

What have the police said?

A representative from Ofordshire Police condfirmed that, although they are gathering information on the circumstances of Michael's death, it is not a major investigation.

They told MirrorCelebs: "Contrary to media reports today (6/1) this is not a Thames Valley Police Major Crime investigation.

“As part of Thames Valley Police’s investigation on behalf of Oxfordshire Coroner into this unexplained but non-suspicious death, officers are establishing facts which includes taking statements.

“This is standard practice in cases such as this to allow the Coroner to determine the circumstances of the death.”

Was he alone?

In the days before his death? No. A flood of visitors descended on the pop star’s home, proving the star was NOT a loner.

Exclusive pictures published by The Mirror showed at least ten people arriving at the large detached house in the lead-up to Christmas Day, when the singer was found dead.

His godson Roman Kemp – son of Spandau Ballet star Martin and his wife Shirlie, who was George’s backing vocalist in Wham! – told how the singer planned a Boxing Day meal before his death.

How was the state of his health?

There was no evidence of George suffering from any terminal diseases.

However, he secretly checked into a clinic the year before his death, which specialises in a modern alternative to electric shock treatment.

It's believed he spent up to a year at the £70,000-a-week Küsnacht Practice overlooking Lake Zurich in Switzerland.

While it is not known exactly which treatments George had, the clinic specialises in repetitive transcranial magnetic stimulation and has one of only two TMS machines in the country.

The therapy involves placing a magnetic device connected to the machine above the head, which stimulates nerve cells in a bid to help combat severe depression.
